AMD Radeon RX 7900 XT

¿El punto de referencia en red dead redepmtion 2 es con fsr activado o desactivado? Supongo que está encendido, fps promedio con fsr apagado alrededor de 70 fps. lo probé

No FSR or DLSS in all those tests. We're not using the integrated benchmark, but our own test scene

My new build uses a MSI 6800 XT Trio...

This is with an undervolt on the gpu through AMD official drivers in the performance section. How does such a giant cooler (this thing is a massive 6800 XT) still manage a 99 celsius hotspot playing God of War no matter what I do (including high fan curve, stock fan curve, I tried it all)

I think something is wrong with it, just doesn't seem right. So, I am refunding this and using the store credit to go towards a 7900 XT for $899, there is an aftermarket one not AMD reference model for $899 I can get. I will gain 40-45 fps in God of War, and lose probably 25 celsius on the hotspot. (also this is drawing 280-290 watts in gaming) so won't even be using more electricity for both of these gains

For $300 more, that's honestly not a bad deal.

Since it is an aftermarket cooler as well, I don't think I will run into any of the same issues listed in many reviews. AMD has also said a driver fix for fixing media playback power draw is done or almost done... so I mean, 7800 XT gets a lot of hate, but $899 for a superior aftermarket version I think is a fair deal honestly. I am gaining 40-45 fps in several titles at 1440p.

I think it depends. If the XTX is priced fairly and the XT is just an attempt to cash grab, yes these could see a price cut (also depending on where the 4070 and 4070Ti land). If, on the other hand, it's the XT that is priced fairly and the XTX is selling at a discount, to undercut the 4080, AMD may not be happy with two discounted top-end SKUs on their hands at the same time.

Objectively, if people think that the RX 7900 XT is a cash grab, then won't the RTX 4070 Ti @ 899 be worst? In Nvidia's own benchmarks, the 4080 12GB (now renamed to 4070 Ti) is about 20% worst in performance, relative to the RTX 4080. So the 4070 Ti should perform closely to the RTX 3090 Ti in most cases. I feel the former will fall short at 4K, as the lower memory bandwidth is going to have an impact to both RT and higher resolution performance. Its got a bigger cache to make up for the smaller memory bus, but like what we have seen with AMD cards, the cache size is mostly in line with the target resolution, i.e. 1440p, and once the cache is insufficient, there will be a noticeable performance penalty.

USB-C with DP 1.2 passthrough

little typo there

does anyone know if the RDNA3 now supports VRR on LG oled C9 (<-this specific model, not later ones)

@W1zzard

In your experience over the years, is a vapor chamber based gpu subject to performance degradation / increased temperatures after 10+ years of usage? Doesn't the water in the vapor chamber eventually evaporate?

if the system is properly sealed why would the water evaporate and to where. Unless it's badly build that shouldn't happen. Water or gas shouldn't be able to pass through solid matter

Anyways, great sale on a 7900 xt reference (759 bucks no tax brand new, shipped and sold by amazon so I know its legit, and comes with the free game last of us), just nabbed one. Just worried about longevity, I expect my 5800x3d and 7900 xt rig to last me ten years. my gtx 1070 laptop lasted me 6 years and it was far inferior of a setup, so I see no reason this setup won't last me ten years as long as I adjust settings, compromise with FSR, play backlog games, etc.

also, one more question, are all reference cards made by AMD? like if I buy a reference card from xfx or sapphire, its still made by AMD directly since its a reference card? they just put it in their own box? I find it a bit confusing.

Last question, reference 6800 XT had a graphene paste, so you never wanted to open the reference 6800 xt, cause that paste was awesome... on your breakdown of this one, it looks like AMD went away from that?

edit: last question I promise this time... this card has a type C port you say in the review can be used with a VR headset, well my monitor the NZXT 1440p monitor, has a type c DP as well, so does that mean I can buy a type c dp 2.1 to type c dp cable... and run this card to my monitor with a type c to type c cable? I just need a type C cable that specifically says its a DP compatible cable?

sorry i worded that last question weirdly... not sure how to word it...

Water won't permeate through the walls of a copper heatpipe tube like Helium will - the molecules are too large.

You're thinking of the defective vapor chambers that tarnished the 7900-series at launch. The issue there was a manufacturing mistake where insufficient water was properly injected before they were vacuum-pumped and soldered closed. If your vapor chamber works when you get it, the vapor chamber will outlast everything else about the card - guaranteed.

thank you this is good to know, W1zz nm about the questions

So really in rasterization, we are really only seeing a 15% uplift over last generation 6950XT? Not very impressive when I can go out and buy a 6950XT for $575 with a $99 copy of Starfield thrown in for free....

What am I really missing with this generation? I undervolt, so power is not so much of an issue, I play multiplayer games, so won't use Ray Tracing and DLSS and FSR are really a non-issue for me at 1440p.....

Maybe that it has 20 GB of VRAM vs 16 GB of VRAM, that can play crucial as we move forward.

And AV1 encoding

 

[Footman]

Yes, perhaps the AV1 encoding, but I don't often encode, so that would not convince me to wait. I probably would have sprung for the GTX 4070 for my upgrade, but the 6950 will still be faster at plain rasterization and as I was going to buy Starfield the AMD card works out $125 cheaper for me.... 16Gb VRAM vs 20Gb is no great loss at 1440P

Thanks for the information, for what I do with my pc I wont miss this.

 

[THU31]

68 billion colors? Just 1 billion short of being nice.

Only Dolby Vision uses 12 bits for HDR, but I don't think there's any DV content on PC (you can't even play pirated DV movies) . It's irrelevant anyway. The difference between 8-bit with dithering and 10/12-bit is imperceptible. Those bit depths are only needed during production (same with 24/32-bit audio).

Wrong. DV uses from 8 to 10 bits depending on the color space used. The rest is for the so called enchancement layer metadata.

Edit: DV content for consumption is also available on PC, although it's a niche.

Edit 2: Please don't even get me started on audio.

Edit 3: I got so triggered by this post that I had to respond on a claim-per-claim basis, or should I say misinformation-by-misinformation basis.

It's not a big difference. Just buy whatever you want, same thing. But buy Nvidia because AMD sucks .

 

[palladino.al]

hahaha a war will start soon haha
At this point, what would be the card that will last the longest over time? consider that I have had my 2060 since 2018

Nvidia seems to have longer driver support lately.
